A projector includes: a plurality of light modulating devices; a light combining optical device having a plurality of light incidence planes that faced a corresponding one of the light modulating devices, the light combining optical device configured to combine the color lights modulated by the plurality of light modulating devices; and fixing members each having a plate-like base in which an opening is formed, the fixing members configured to fix the light modulating devices to the light combining optical device, the light modulating devices are fixed to the fixing members in a state in which the light modulating devices are inserted in the openings.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A projector, comprising: a plurality of light modulating devices configured to modulate each of a plurality of color lights, each light modulating device having a light-incident side end and a light-exiting side end; a light combining optical device having a plurality of light incidence planes that face a corresponding one of the light modulating devices, the light combining optical device configured to combine the color lights modulated by the plurality of light modulating devices; and fixing members configured to fix the light modulating devices to the light combining optical device, each fixing member having a plate-like base in which an opening is formed, a pair of rising sections extending in a direction perpendicular to the plate-like base from a pair of end edges on opposing ends of the plate-like base, and a pair of protruding sections of which a protruding section of one rising section protrudes toward the other rising section and a protruding section of the other rising section protrudes toward the one rising section, the light modulating devices are fixed to the fixing members by being inserted into the openings such that one of the light-incident side end or the light-exiting side end of each light modulating device abuts against the corresponding protruding sections.
2. The projector according to claim 1 , wherein each of the light modulating devices is fixed to a corresponding one of the fixing members in a state in which a light incident-side end and a light exiting-side end of the light modulating device jut from a plate face of the base.
3. The projector according to claim 1 , wherein the light modulating devices each have a light incident-side end and a light exiting-side end, one of which is fixed to the protruding sections.
4. The projector according to claim 3 , wherein the fixing members each include polarizer supporting sections bent from the protruding sections toward the light exiting side.
5. The projector according to claim 1 , further comprising: supporting members each having a plate-like section and four pins projecting from four corner portions of the plate-like section toward the light incident side and supporting a corresponding one of the fixing members.
6. The projector according to claim 1 , further comprising: a cooling device that sends air to the light modulating devices; and the air is split into the light-incident side and the light-exiting side of each light modulating device, and circulates along the light-incident side end and the light-exiting side end.
7. The projector according to claim 6 , wherein the light modulating devices have right and left side edge parts, and the right and left side edge parts and the pair of rising sections form a passage for air sent from the cooling device.
